Research on optimization of conductivity of multilevel fractures in tight sandstone based on similar circuit principle

open access: yesEnergy Science &Engineering, Volume 12, Issue 6, Page 2627-2642, June 2024.
The post‐pressure fracture network is equivalent to a high‐permeability zone, and the reservoir numerical model is established to optimize the equivalent hydraulic conductivity of the fracture network. Based on the discrete element theory, the fracture expansion and its geometric parameters after volume fracturing of dense sandstone are simulated, and ...

Long‐term fracture conductivity in tight reservoirs

open access: yesEnergy Science &Engineering, Volume 12, Issue 3, Page 1187-1199, March 2024.
The fracture conductivity decreases with the increase of displacement time under the displacement of formation water and fracturing fluid, and the decrease of fracture conductivity under the displacement of fracturing fluid with time is greater than that of formation water displacement. The conductivity increases with the increase of sand concentration,

An Innovative Production Prediction Model for Fractured Horizontal Wells in Low‐Permeability Gas Reservoirs Accounting for Proppant Embedment

open access: yesInternational Journal of Energy Research, Volume 2024, Issue 1, 2024.
This study focuses on addressing the challenge of accurately calculating the production caused by stress sensitivity and proppant embedment during actual production in low‐permeability gas reservoirs. To achieve this, a stress sensitivity model in the matrix zone and a proppant embedding model in the fracture area are established.

Division and Effect Evaluation of Fracking Outburst Elimination Zones in Surface Extraction Wells of Coalbed Methane

open access: yesGeofluids, Volume 2024, Issue 1, 2024.
Surface hydraulic fracturing is an important measure for increasing reservoir permeability, which has advantages such as engineering safety and a large impact range and can be implemented ahead of the mine’s underground engineering. However, its underground outburst reduction range and effect are rarely reported, and there is a lack of connection with ...

Study on the Long-Term Influence of Proppant Optimization on the Production of Deep Shale Gas Fractured Horizontal Well

open access: yesApplied Sciences
As shale gas development gradually advances to a deeper level, the economic exploitation of deep shale gas has become one of the key technologies for sustainable development. Large-scale, long-term and effective hydraulic fracturing fracture networks are

Drilling Deadlines and Oil and Gas Development

open access: yesEconometrica, Volume 92, Issue 1, Page 29-60, January 2024.
Oil and gas leases between mineral owners and extraction firms typically specify a date by which the firm must either drill a well or lose the lease. These deadlines are known as primary terms. Using data from the Louisiana shale boom, we first show that well drilling is substantially bunched just before the primary term deadline.

Evaluation of sintered bauxite proppant for binary enhanced geothermal systems

open access: yesGeomechanics and Geophysics for Geo-Energy and Geo-Resources
Solid granular proppant particles are widely used in oil and gas development to sustain permeability through fractures after hydraulic stimulation. Similar proppants are of interest for geothermal applications where the goal of sustaining permeability is

A Generic Fracture Conductivity Model for Partially Propped Fracture Networks with Proppant Embedment and Proppant Pack Deformation

open access: yesProcesses
Hydraulic fracturing involving proppant injection is currently the most effective technology to stimulate tight, unconventional reservoirs. The conductivity offered by the created propped and unpropped fracture segments is directly linked to the well deliverability.

A Multi-Parameter Integrated Model for Shale Gas Re-Fracturing Candidate Selection

open access: yesEnergies
With the continuous advancement of shale gas field development, well productivity following initial hydraulic fracturing often declines due to mechanisms such as proppant embedment and fracture conductivity degradation.
